interesting observation. I don't know how the specifically is playing into it. Overall headcount is the bigger issue. It's like the restaurant that has sections blocked off due to no staff, except the airlines still have the flights scheduled. They can't serve the passengers, there aren't enough bodies on the tarmac, maintenance, crews to handle the flight load. Put that mix in motion, and at some point Plane #1 which flies A to B, B to C, C to D, somewhere in b/t there's a delay somewhere, and crew on #1 can't get to C to get to Plane #2 to take it C-E. because Plane #2 needs crew from Plane #1. Plane #2 C-E gets canceled. crews timed out, or otherwise unavailable. nothing wrong with the plane, there's no weather issues....And if there are those issues. big problems.
